KÖLLEMANN is world market leader in the area of preheaters

And once again, a Köllemann preheater with a throughput of 51 tph leaves our production and goes on its journey to the customer

KÖLLEMANN preheaters are used to heat up petroleum coke. Petroleum coke is a residue formed as a by-product of petroleum refining and is made of almost pure carbon. KÖLLEMANN preheaters perform the heating process and heat the product from at least 0°C to approx. 200°C. The heated petroleum coke is then mixed with hot pitch in a kneader. The paste formed is then pressed into a block shape. These blocks are then baked and represent the anode, which is used in the Hall-Héroult process (electrolysis) for the reduction of aluminium.
